Dear Kernel Maintainers,
Kurobox-Pro (and variants) need more commands sending to UART1 to shutdown.
So here I make this patch series to let current qnap-poweroff implementation
be able to handle such case.
Here I give 3 patches, for 3 different kernel subsystems respectivelay:
- Patch 1/3: System reset/shutdown driver
- Patch 2/3: Open firmware and flattened device tree bindings
- Patch 3/3: ARM/Marvell Dove/MV78xx0/Orion SOC support
Ryan Tandy, the issue reporter, and I have already tested those changes on
Linkstation/KuroBoxPro devices, and confirmed it's working well.
Merry Xmax and look forward to your feedback!
Changes:
v0 => v1:
- Update 0003 to split kuroboxpro related code into kuroboxpro-common.c
v1 => v2:
- Split off linkstation/kuroboxpro related code to linkstation-reset.c
Because linkstation before kuroboxpro also need this driver to power
off properly. It's more proper to call it linkstation driver.
v2 => v3:
- Split off devicetree bindings doc into a separate patch.
- Add device-tree patch to make Linkstation LS-GL and KuroBox Pro to
use the newly created linkstation-reset driver.
- Remove the unused one-byte command sending case in linkstation-reset
driver.
v3 => v4:
- Reduce the global singleton variables by moving to structure, which makes
the driver easy to support reboot function in the future. Thanks to
Florian Fainelli.
- Simplify the power_off function registration. Thanks to Florian Fainelli.
- Drop DT binding doc.
